Warnings
Warnings tell you about dangerous conditions that could lead to death or serious injury to
the user or patient that can occur if you do not obey all of the instructions in this manual.
1. WARNING: To avoid over- or under- infusion, always verify that the brand and size of the
loaded syringe are the same as the brand and size displayed on the screen before starting
an infusion. Failure to do so may result in an inaccurate delivery of medication, resulting in
patient injury or death.
2. WARNING: To avoid incorrect or inappropriate configuration of the pump, the
Configuration menu must only be selected by qualified persons or authorised personnel.
Incorrect pump configuration could lead to inappropriate infusion resulting in patient
injury or death.
3. WARNING: This equipment is not suitable for use in the presence of flammable
anaesthetics, oxygen-enriched or explosive atmospheres. The use of the device in such
atmospheres may lead to explosion or fire.
4. WARNING: To avoid possible malfunction of the pump, do not expose the pump to X- rays,
gamma rays or ionizing radiation, or to the RF interference or strong electric/magnetic
fields emitted (for example) by diathermy equipment or mobile telephones. If the pump is
used in the presence of, or in combination with Magnetic Resonance Imaging (MRI)
machines it must be protected from the magnetic field emitted by such equipment.
Malfunction of the pump can cause incorrect infusion or loss of infusion resulting in
patient injury or death.
5. WARNING: Operation of the pump outside the temperature limits defined in the
specification may result in erroneous operation. Ensure that the temperature is within the
specified limits. Failure to do so may result in patient injury or user injury.
6. WARNING: In order to ensure that the intended infusion is performed, data must be
entered correctly. Likewise before confirming any displayed data the user should ensure
that it is correct. Failure to do so may result in compromised function of the product,
patient injury or user injury.
7. WARNING: Failure to respond promptly to an alarm may result in patient injury or death.
8. WARNING: Failure to follow the Service Manual’s maintenance schedule recommendations
may result in compromised function of the product and lead to patient injury or death.
9. WARNING: It is essential that clinical staff remain within visual and audible range of the
pump so that critical alarms can be seen or heard and responded to.
10. WARNING: The user should ensure that the performance offered by the pump is fit for the
intended purpose. Failure to do so may result in compromised function of the product,
patient injury or user injury.
11. WARNING: When the pump is carrying out an infusion, to ensure that electrical safety is

Aneasthesia syringe pump
12. WARNING: Correct management of battery charging is essential to ensure that the pump
can operate on batteries for the time specified. Failure to do so may lead to impaired
functioning of the pump, resulting in patient injury or death.
13. WARNING: Do not use a faulty pump. If the pump develops a fault then an alarm will sound;
the display will indicate a FAULT condition and the pump will fail to infuse. Incorrect
performance of the pump can cause complications resulting in patient injury or death.
If the pump develops a fault then it must be referred to a suitably qualified engineer or
returned to Graseby Medical in order to have the fault rectified.
14. WARNING: Failure to use the mains lead clamp means that the pump may be accidentally or
erroneously disconnected from the mains. Although there is battery backup in case this
happens, the battery may not be sufficiently charged. Consequently there is a risk of the
pump not functioning, which could lead to patient injury or death.
15. WARNING: If an occlusion alarm occurs, immediately clamp the line to eliminate the
possibility of a bolus being delivered to the patient. Then inspect the fluid pathway for kinks,
clogged catheter, etc. in order to remove the occlusion prior to restarting the infusion. An
unintentional bolus of medication can result in patient injury or death.
16. WARNING: Use only the syringes and administration sets listed in the Specification at the
end of this manual. Failure to do so may result in an inaccurate delivery. Graseby Medical
does not guarantee performance of the pump if syringes other than those listed are used.
Incorrect function or performance of the pump can cause complications resulting in patient
injury or death.
17. WARNING: The volume of fluid contained in the connecting tubing is a residual amount and
will not be infused. Hence this extra volume of fluid must be allowed for when initially filling
the syringe and purging the system. Under-delivery of medication can cause complications
resulting in patient injury or death.
18. WARNING: To avoid patient embolism, ensure that the patient tubing is purged of all air
bubbles before administering any medication. The pump provides a purge facility to assist
with this process. The presence of air within the medication can result in complications
leading to patient injury or death.
19. WARNING: To avoid syphoning of the syringe contents (free flow), ensure that the syringe is
correctly loaded into the pump, that the syringe plunger is properly engaged by the pump’s
actuator and that the pump is placed not more than 80cm above the infusion site.
Syphoning can result in over-infusion leading to patient injury or death.
20. WARNING: To avoid over-infusion, do not purge the infusion line when the administration
set is connected to the patient. Over-infusion of medication can result in patient injury or
death.
21. WARNING: To avoid the pump becoming detached from an IV pole always make sure that
the pump is securely fixed to the pole. Always check the security and stability of the
assembly with the pump mounted.
If no IV pole is used make sure that the pump is completely stable on a horizontal surface.
Failure to observe this warning may cause damage to the 3400 Syringe pump and harm
the operator or the patient. As a result, the operator or patient may suffer direct injury, or
the 3400 Syringe pump may fail to operate correctly, leading to patient injury or death.

Aneasthesia syringe pump
22. WARNING: Following a significant liquid spill onto the pump, it should be wiped dry and
inspected by service personnel before being returned to service. Failure to do so may
result in compromised functioning of the pump, leading to patient or user injury or death.
23. WARNING: When using a syringe smaller than 50/60 ml the occlusion pressure will
increase as the diameter of the syringe decreases, i.e. the smaller the syringe the higher
the pressure
Cautions
Cautions tell you about dangerous conditions that can occur and cause damage to the pump
if you do not obey all of the instructions in this manual.
1. CAUTION: Refer all service, repair and calibrations only to qualified technical personnel.

Anaesthesia Syringe pump
Introduction
Thank you for choosing a Graseby 3400 Anaesthesia syringe pump. This Instruction
Manual contains important information on operating and looking after your pump. So that
you are completely familiar with all of the pump’s features, please take the time to read
this manual before switching on the pump. It is important that all users of the 3400 have
been trained in how to use the pump.
The pump is a micro-computer controlled device developed by Graseby Medical for the
administration of sterile liquids. This compact, robust pump is designed to sit on a table
top or to be pole mounted.
It can be configured to work with one of a range of brands of syringe, and the the brand
that the pump is presently Configured for is displayed.
The pump caters for syringe sizes of 5, 10, 20, 30, 35, 50 and 60 ml, the size is
automatically sensed and displayed.
The pump can be set to dispense liquids at maintenance rates of 0.1 to 400 ml/hr in steps
of 0.1 ml/hr. The rate is entered via a numeric keypad and can be adjusted whilst the
pump is infusing. Similarly the bolus infusion rate can be adjusted from 0.1 to 1200 ml/hr
in steps of 0.1 ml/hr.
A dose rate calculation is also possible, allowing the infusion rate to be programmed in a
range of units, including ml/hr, mg/kg/hr, mg/kg/min, mg/kg/hr, mg/kg/min, mg/hr and mg/
hr.
A handsfree preset bolus allows a predetermined bolus to be set and delivered, allowing
the user to concentrate on the patient's response to the medication during the bolus
infusion.
The pump keeps a running total of the volume of liquid infused, even when an infusion is
stopped and restarted.
Safety features have been built into the pump and its software. The pump carries out self
testing routines every time it is switched on. Users are warned of such incidents as
occlusion or power failure by both visible and audible alarms.
The pump can be run from AC mains power (recommended) or from internal rechargeable
batteries which give more than ten hours of use. All the controls are clear and easy to
use. The pump incorporates a graphic liquid crystal display that provides the user with a
constant indication of the pump’s operation.

Switching on
Connect to AC power. (For battery operation refer to Section 11). Insert
the AC power lead into the rear of the pump. Secure the mains lead with
the clamp as shown in Figure 2, to prevent it from being accidentally pulled
out of the pump.
Figure 2 Mains Lead Clamp
The AC power indicator lamp will illuminate when connected to AC power.
Press the ON key to switch on the pump. A brief self-test procedure will
then be performed, during which a bleep will be heard. The pump is now in
its ‘set-up’ mode, ready for an infusion rate to be set.
WARNING: Do not use a faulty pump. If the pump develops a fault then an
alarm will sound; the display will indicate a FAULT condition and the pump
will fail to infuse. Incorrect performance of the pump can cause
complications resulting in patient injury or death.
If the pump develops a fault then it must be referred to a suitably qualified
engineer or returned to Graseby Medical in order to have the fault rectified.
WARNING: Failure to use the mains lead clamp means that the pump may be
accidentally or erroneously disconnected from the mains. Although there is
battery backup in case this happens, the battery may not be sufficiently
charged. Consequently there is a risk of the pump not functioning, which
could lead to patient injury or death.

10.5
Occlusion
OCCLUSION
ALARM TYPE
Pulsing loud alarm (silenceable).
CAUSE
There is a pressure buildup on the syringe plunger
clamp, probably because of a blocked infusion line.
The infusion has stopped.
ACTION
Silence the alarm.
WARNING: If an occlusion alarm occurs, immediately clamp the line to
eliminate the possibility of a bolus being delivered to the patient. Then inspect
the fluid pathway for kinks, clogged catheter, etc. in order to remove the
occlusion prior to restarting the infusion. An unintentional bolus of medication
can result in patient injury or death.
To remove the pressure, swing the syringe plunger clamp
away from the body of the pump and slide to the right. Then
deal with the occlusion. Reposition the plunger clamp. If the
START key is pressed before the plunger has been opened
the pump will not run and the message RELEASE CLAMP
will be displayed briefly. Restart the infusion as described in
section 6.
10.5.1
Occlusion sensing system
The pump has a sensitive, internal occlusion pressure detector which detects the
pressure build-up on the syringe plunger, an occlusion is usually caused by a
blocked infusion line. The pressure at which the pump's occlusion alarm
activates is adjustable from 1.85 kg to 7.42 kg (250 mmHg to 1000 mmHg). The
factory set occlusion pressure is between 5.7 kg and 6.2 kg (767 and 834 mmHg
respectfully for a perfect BD 60 ml syringe).
10.5.2
Time to alarm following occlusion
The time to alarm following occlusion is due to a number of factors which include
the compliance in the syringe and infusion line and mainly the infusion rate. Under
normal conditions and using a non compliant infusion line (i.e. a thick walled nonflexible line), the time to alarm following occlusion at 1.0 ml/hr is approximately
27 minutes at an occlusion pressure setting of about 350mmHg, using a BD 50ml
syringe.
Page 14
Graseby 3400
Anaesthesia Syringe pump
This time can be further reduced by reducing the internal occlusion pressure.
A lower pressure will give a shorter time to alarm but there may be an increase
in false alarms. The maximum time to alarm following occlusion will occur at
the lowest settable infusion rate of 0.1ml/hr. At rates as low as this the time
to alarm is likely to be several hours unless smaller syringe sizes are used.
10.6
The nearly empty alarm system
The pump has a unique intelligent nearly empty alarm system. One of two
messages is displayed:
This alarm only operates at infusion
rates at or below 100 ml/hr.
< 3 mins to END
ALARM TYPE
Intermittent quiet alarm.
CAUSE
The syringe is nearly empty, there are less than 3 minutes
before the syringe enters the KVO mode (section 10.7).
The pump is continuing to infuse at the set rate.
ACTION
This alarm can be silenced. If you wish to continue
infusing fill, prime and reload the next syringe (section
2.2). If not, stop the infusion when the end of infusion
alarm sounds (section 10.7/10.8)
NEARLY EMPTY
This alarm operates at infusion rates
above 100 ml/hr, or when a syringe is
loaded with approximately 2.5 cm or
less syringe plunger travel remaining.
ALARM TYPE
Intermittent quiet alarm.
CAUSE:
The syringe is nearly empty. The pump is continuing
to infuse at the set rate.
ACTION
This alarm can be silenced. If you wish to continue
infusing, fill, prime and reload the next syringe (section
2.2). If not, stop the infusion when the
EMPTY/OCCLUSION alarm sounds (section 10.8)

Infusion ended (KVO mode)
ENDED (KVO = .5)
This alarm only operates at infusion
rates at or below 100 ml/hr and
follows the "<3mins to END" alarm.
ALARM TYPE
Pulsing loud alarm (silenceable).
CAUSE
The infusion has stopped. The pump is running at a rate
of 0.5ml/hr or less, if set rate is less, to keep the vein
open.
ACTION
Press the alarm silence key to silence the audible alarm.
If you wish to continue the infusion fill, prime and reload
the next syringe (section 2.2). The small amount of drug
left in the syringe can be infused at the set infusion rate by
stopping and re-starting the pump. To stop the infusion
press STOP.
Note: the KVO mode is not operative when the pump is
controlled by an external computer.
10.8

11. Battery
operation
When the pump is switched on but not connected to the AC power supply it will (if the
batteries are charged) operate as if connected to the AC power, except that:
•
the AC power lamp will not be illuminated and the following message will be
displayed during operation...
ON BATTERY
•
a ‘B’ will be shown within the pump running indicator arrow on the right of
the display,
•
the low battery alarm is operative (section 10.11),
•
the batteries will be fully charged if the pump has been connected to mains
power for at least 14 hours. When fully charged the batteries will power the
pump for more than 10 hours.
WARNING: Correct management of battery charging is essential to ensure that the pump
can operate on batteries for the time specified. Failure to do so may lead to impaired
functioning of the pump, resulting in patient injury or death.

12. Positioning
the pump
The pump should be positioned and operated horizontally. It may be placed on
a flat stable surface or mounted on a vertical IV pole or rail using the pole
clamp.
CAUTION: If the pump is used in close proximity to a fluid bag(s), it should where
possible, not be mounted directly underneath the fluid bag(s). This is to minimise
the possible risk of damage to the pump from fluid ingress should the bag
rupture or leak during use.
WARNING: To avoid the pump becoming detached from an IV pole always make
sure that the pump is securely fixed to the pole. Always check the security and
stability of the assembly with the pump mounted.
If no IV pole is used make sure that the pump is completely stable on a horizontal
surface. Failure to observe this warning may cause damage to the 3400 syringe
pump and harm the operator or the patient. As a result, the operator or patient
may suffer direct injury, or the 3400 syringe pump may fail to operate correctly,
leading to patient injury or death.
WARNING: Following a significant liquid spill onto the pump, it should be wiped
dry and inspected by service personnel before being returned to service. Failure
to do so may result in compromised functioning of the pump, leading to patient or
user injury or death.
13. Cleaning and maintenance
Cleaning
The pump may be decontaminated by wiping it with a mild disinfectant solution.
For example, the disinfectant solution may be made by using
sodiudhypochlorite diluted with water, to give a solution of 0.1% available
chlorine. The chlorine concentration will be stated on the product label. The
solution must be freshly made and used within 24 hours of preparation.
WARNING: Following a significant liquid spill onto the pump, it should be wiped
dry and inspected by service personnel before being returned to service. Failure
to do so may result in compromised functioning of the pump, leading to patient or
user injury or death.
CAUTION: Do not use cleaning and disinfecting agents other than the approved
ones specified here.
CAUTION: The pump must not be immersed in any liquids or exposed to strong
organic solvents. Wipe off spills immediately, and do not allow fluid or residues to
remain on the pump. Additionally, the pump is not designed to be autoclaved,
steam-sterilised, ETO-sterilised or subjected to temperatures in excess of 45° C
(113° F). Failure to observe this caution may cause serious damage to the pump.

Disposal
When the time comes to dispose of the pump or its accessories do so in the
best way to minimise any negative impact on the environment.
There are three batteries inside the pump that contain harmful lead and sulphuric
acid. First discharge the batteries by operating the pump, then dismantle the
pump and remove all three batteries. Do not open up the batteries as this will
release the acid. Do not incinerate them as they may explode. Separate them
from the everyday waste, as indicated by the graphic symbol on the batteries.
You may be able to use special recycling or disposal schemes. To find out about
these contact your local waste disposal service.
Separate any other parts of the equipment where arrangements can be made for
their recovery, either by recycling or energy recovery. Larger plastic parts are
marked with a material identification code to facilitate recycling.
Important: Existing national or local regulations concerning waste disposal
must take precedence over this advice.
